MACHINE FOR RUBBING STONE.

Specification of Letters Patent No, 9,104, dated July 6, 1852,

lo all 'whom 'it may concern:

Be it known that we, PLEASANT E. RoYsE, of the city of New Albany and county of Floyd and State of Indiana, and IRA REY- NoLns, of Republic, county of Seneca, and State of Ohio, have invented a. new and useful Machine for Rubbing and Polishing Marble and other Stone; and we do hereby declare that the following is a full, clear-,

and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1, is a top view or plan of the machine, with the top or cap od, showing the position of the driving wheel and pinions, levers or arms, and blocks of marble and their position in reference to each other. Fig. 2, is a transverse section on` the dotted line x, of Fig. 1, showing the position of the pairs of cranks, and their connection with the arms or levers. Fig. 3, is a modified transverse section on the dotted line w, of Fig. 1, in which the framework is dispensed with, and the pairs of cranks inverted, so as to work above the top of the box z'.

But to be more particular: A, is the bed stone; B, is the rubber; C, is the arm or lever; D, is beam to which the team may be attached.

E, is main shaft to which the beam and driving wheel are attached.

Z), is the driving wheel; a, the pinlons; g, the frame workl and h, is the cap or top .of the machine.

To enable others skilled in the art, to make and use our invention, we will proceed to describe its construction and operation.

IVe construct the frame work of our machine with suitable sized timbers, in a quadrangular, sexangular, or octangular form, and of suitable dimensions for the desired purpose, uniting the upright timbers with pairs of ties which form its several sides; and to these ties the boxes are attached in which the journals of the pinions revolve, as seen in Fig. 2, of the drawings. In the center of this frame work we place the upright shaft E, to which the driving wheel b, is made fast, and meshes into the pinions, which are radially arranged upon the several sides of the above frame work, so as to revolve on their own axes, while the team, or other power is moving the main shaft and driving wheel. The above pinions are made fast upon the crank shafts, e, which are arranged on the several sides in a radial line with the cranks, f, which are placed about one foot from the center of the machine. These cranks are arranged in pairs, so that when the levers or arms, C, are placed thereon, and the pinions, a, are made to revolve, by the driving wheel, ZJ, it gives the rubber, B, a rotary, or compound elliptic rotary motion. These levers may be slotted and work on stationary pins on the inside or outside of the pinion cranks, instead of the inside cranks f.

The above described frame work may be dispensed with, by making a cast cylinder or bow, i, Fig. 3, about four and a half feet in diameter, and eighteen inches high, with an inside plate, j, which is intended as a bearing for the lower ends of the inside cranks f, as seen in Fig. 3. In this form of construction, the driving wheel and pinions are placed at the bottom of the inside of the cast box or frame, z', thus reversing the cranks, which would in this case revolve above the top of the box or frame, as seen in Fig. 3. The top or cap, k, is secured to the box or frame, i, at, n, by means of nuts and screws, thus securing the whole in a neat, solid, durable and compact form, and makes it convenient for placing or removing the arms or levers from the cranks, when desired, and makes the whole machine very portable and convenient. l

The several pairs of cranks in this machine may be made of any length to secure the desired motion of the rubbers. This may be effected by slides, pins or otherwise, and give any two of the several pair a motion corresponding with the size of the stone desired to be rubbed or polished.

V'e are aware that stationary or fixed wheels have been placed in the center of stone rubbing machines, with cranked pinions revolving on their own axis, and around the said lixed wheels as a common center; therefore We do not wish or intend to claim the arrangement of stationary or fixed wheels around which pinions revolve, to give motion to t-he arms and rubbers. But

Vhat we do claim, as our own invention, and desire to secure by Letters Patent, is-

The arrangement of a revolving center driving wheel, with a series of stationary crank shaft pinions revolving on their own In testimony whereof We have signed our` axes, Whether in Combination With the names before tWo subscribing Witnesses. cranks, f, or stationary, so constructed and PLEASANT E.
